Could Masonic Charges be filed against a Brother from another Jurisdiction? Local ones are tough enough, I couldn't imagine dealing with that across state lines.
I would think that the desire to file charges on a traveling brother would have to be pretty strong to pursue this. The offense would have to be substantial or the person who desires to file should reexamine the internal qualification of himself. In the case of an offense of the magnitude deserving this I would assume both Grand Lodges would probably support it. Also if a person is a MM who is traveling they are under their requirements. I can see some wiggle room here but as I said before if the offense was of a magnitude deserving this then the brother should know better.
...I don't think these "charges" threads are all based on actual events but more or less "What if" scenarios.
